I purchased one from Top T on Amazon, very good service ordered on the 1st and arrived today via Royal Mail special delivery. ?411 for a HK import considering the quality of the phone is ok by me. I did email them before i placed the order and asked where they sourced but the girl who replied stated it would either be an Asia or European version. It does state on Amazon that it would be a gb version but i'll take my chances.
I'm not complaining though especially at the price for it. No import duty as it was dispatched from uk. The girl did mention in her email that they use a dedicated Nokia service centre and if there are any warranty issues with the phone they pay for postage to it. I don't have a problem with it was looking at one on Gumtree but it's worse than ebay for scammers. Absolutely stunning phone and managed to keep my 1020 to replace my iPhone 5 for work so well pleased.
